You're not going to bail on that nice teal Integra are you? Judging by that sweet photo, a bird in hand is worth two in the bush. Your's must be pretty rough mechanically to want to change up. What do you know about this other car? Has it been wrecked, raced, or repainted? At least you know the maintenance history of your car.
Black is the most high maintenance color there is. It shows the slightest bit of dust and gets "swirls" in the paint at the drop of a hat.
